GEORGE M. DWIGHT, F OREGON, ILLINOIS. Letters Patent No. 85,001,1Zated December 15, 1868.

DIIZPROVEMENT' m cuLrIvAroRs.

The-Schedule referred to in these Letters Patent and making pm of the same.

To all whom it may concern r Be it known that I, GEORGE M. DWIGHT, of Oregon, in the county of Ogle, and State of Illinois, have invented a new and improved Cultivator; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, which form a portion of this specification.

Figure 1 is a side view of my improved cultivator.

Figure 2, a top view.-

Figure 3, a'bottom view, and

Figure 4, a side view of the axle of the cultivator, detached from the other parts thereof.

Similar letters indicate like parts in all the drawings.

The shape of the axle A of any improved cultivator is clearly shown in fig. 4.

To the raised central portion of thisaxle, I firmly secure a substantial 'body-platfonn, C, and to the front end of this platform I firmly secure a transverse draught bar, D. V The tongue E of the cultivator is jointed to the front end of the body-platform O, by means-of the vertical bolt a, which passes through the tongue, at a point distant about one-fourth the length thereof from its rear end.

The rear end of the tongue E is jointed to the fiont end of the guiding-lever F, by means of the metallic plate e, which is pivoted to the rear end of the bod platform 0, by the bolt j.

A projecting front portion of the said plate e passes a considerable distance into a slitted recess in the rear end, of the tongue, and is pivoted thereto by the bolt f, as shown in fig. 1.

It will therefore be perceived that the guiding-lever F gives the operator the power of instantly turning ihe cultivator to the right or left, out of the line of draught, whenever it maybe desirable to do so. for more eiiicient cultivating-purposes, or for preventing injury to the articles that may be cultivated by the assistance of this implement.

The whiiile-trees q q are attached to the draughtchains 1) p, which are themselves connected to the draught-plate z, which is pivoted to the under sideof the rear end of the body-platibrm O, as shown in fig. 3.

The said draught-chains p 1) pass from the front end of the draught-plate l1 outwardly to and around grooved pulleys, which are respectively pivoted to the under sides of the ends of the draught-bar 1).

The series of cultivator-points i i is secured to the inclined arms g g, which respectively descend from their jointed connections with the parallel beams G G, and which are respectively retained in any desired inclined position, by means'of the segment-shaped perforated arms hh, as shown in fig. 1.

The front ends of the parallel beams G G are indirectly jointed to the draught-bar D,-in such a manner as to enable the rear ends of said beams to be laterally and vertically vibrated, as circumstances may require, to wit, the flaring-metallic arms 1: r, at the front ends of the beams G G, are pivoted to the peripheries of the disks d d, by the pivots s s, and these disks d d are'pivoted to the supporting metallic plates 1) b, which project rearwardly from their firm connection with the draught-bar D, as shown in the drawings. portions of the parallel beams G G may be connected with each other by any suitable means.

A metallic arch-plate, 7c, is combined with each beam- G, in the manner represented in the (h'awings.

' A screw-shank, at the forward end of each of said arch-plates 70, passes through its respectivesupporting-plate b, and is secured therein by a screw-nut, t,

on the under side of each of said plates, as shown in fig. 3. The after ends of the said arch-plates'lc 7c pass through slits in the parallel beams G G, and the said arch-plates are connected with each other by means of the rod j, and the pairs of nuts which work on the.

catches which work into the same, enable the beams G G to be elevated and retained at any desired distance above the ground, and also to be depressed any desired distanceinto the ground.

It will therefore be perceived that the peculiar construction of my improved cultivator enables the operator to exercise complete control over the position of the parallel beams G G, and the cultivating-points descending therefrom, enabling the same to be elevated, depressed, or moved to the right or left, as circumstances may require.

Having thus fully described the construction and operation of my improved cultivator, I

What I claim therein as my invention, and desir to secure by Letters Patent, is-

1. The combination of the body-platform G, with the draught-bar D,the tongue E, and the guiding-lever F, in such a manner that when the said body-platform is combined with the bent axle A, the said draught-bar will be in the proper relative position for the combination therewith of the parallel beams G G, and the notched arch-plates k h, all substantially in the manner and for the purpose herein setfolth.

,2. \Vhen the parallel beams G G are combined with the draught-bar I), substantially in the manner here i ber, 1868. p
